I hate people telling me to stay single

I'm 24 years old never had a girlfriend and I hate it (I've been trying since i was 15 but no luck). But what really pisses me off is when I tell people this, they tell me to "stay single" or "You're should be lucky" but these mother fuckers be in relationships or seeing somebody. Hell, some of them even canceled on hanging out with me to be with their S.O (which is fine btw) so why the fuck are they telling ME to stay single
